Moxa’s Universal PCI CP-132UL series meets the new slot standard for expansion boards, and works with both 3.3V and 5V PCI slots. The CP-132UL series offers 2 independent RS-422/485 serial ports for connecting data acquisition equipment and many other serial devices to a PC and compatible systems. It provides a reliable communication link (RS-422/485) over a long distance (up to 4000 ft), and is suitable for industrial environments. The following topics are covered in this chapter: T Overview T Features T Package Checklist Overview Industio—The Industrial Multiport Async Solution Moxa Industio products are smart, multiport serial I/O solutions for industrial applications. The CP-132U Series boards, including CP-132UL V2, and CP-132UL-I V2 (the previous version is CP-132U-I V1), are designed for a 32-bit PCI bus with the Plug and Play and Universal PCI feature. They offer 2 independent RS-422/RS-485 serial ports for connecting data acquisition equipment and many other serial devices to the PC and its compatible systems. Industio products provide a reliable communication link over a longer distance (up to 4000 ft), and are suitable for industrial environments. Connections with point-to-point full-duplex or multidrop half-duplex are available to meet user’s various needs. Each port can control up to 32 devices in a multidrop environment. ADDC™ (Automatic Data Direction Control) for RS-485 To make it easier to manage 2-wire RS-485 half-duplex connections, ADDC™ (Automatic Data Direction Control) intelligence is built into each CP-132UL series board, eliminating the need for software interference. This means that Windows applications can manage RS-485 ports, without the need to write extra code for controlling the half-duplex protocol. With their well-designed and fine-tuned device driver, CP-132UL series boards make full use of the 128 byte Tx/Rx FIFO and on-chip H/W and S/W flow control, so that they can transfer data without loss even at speeds as high as 921.6 Kbps, providing a reliable, high performance solution for serial multiport communications. Termination Resistors Ready for RS-422/485 Termination Resistors are already installed on the CP-132UL series boards, eliminating the headaches involved in determining the proper impedance for the resistors. For more details, refer to the “Connection Cable and Cable Wiring” chapter. Surge/Isolation Protection To prevent boards from being damaged by lightning or high potential voltage, CP132UL Series boards have built-in surge protection. An optical isolation option (2000V), and surge protection option (max. ESD of 16 KV, max. EFT of 2 KV) are also available in this series. Both of these features provide protection when the boards are used in critical or harsh factory-type environments. 1-2 CP-132U Series User’s Manual Introduction PCI Solution The board complies with PCI Spec. 2.1 and does not require either switches or jumpers. The hardware configuration for the IRQ and I/O address is automatically assigned by the PCI BIOS. This means that the board MUST be plugged into the computer first before installing the driver software. For more PCI information, refer to the Technical Reference Appendix. Universal PCI The 32/64-bit PCI local bus specification specifies both 3.3V and 5V connector types for the PCI hardware. Moxa’s universal PCI card allows the user to plug into both a 3.3V/5V and 32/64-bit slot. Operating System Support The CP-132UL series is compatible with most major industrial platforms, including Windows 2000/XP/2003, Windows NT, Windows 95/98/Me, DOS, and Linux. MOXA device drivers are provided for smoother installation, configuration, and performance. In this manual, sections for MOXA Windows 2003, Windows 2000/XP, Windows NT, Windows 95/98, DOS, Linux, and SCO are included. MOXA Serial Comm Tools For application development, MOXA provides an easy-to-use serial communication library called PComm that runs under Windows NT/2000/XP/2003 and Windows 95/98. You can use this library to develop your own applications using Microsoft C, Turbo C, Assembly, QuickBASIC, Turbo Pascal, Clipper, Visual Basic, Visual C++, Borland Delphi, etc. Utilities, such as Data Scope, Monitor, Terminal Emulator, Diagnostics, etc., are included for debugging or monitoring the communication status, terminal emulation, or even file transfer.

CP-132U Series User’s Manual 4-3 RS-485 Programming If you intend to use your CP-132UL Series board for RS-485 applications, you can refer to the RS-485 programming guide below, and also see the chapter, “Connection Cables and Cable Wiring,” for more details about RS-485 operation. The CP-132UL Series supports only 2-wire half-duplex RS-485 communication. In this case, the data+/- pins are used for both data transmitting and receiving, depending on the mode selected. Moxa’s own ADDC™ (Automatic Data Direction Control) technology is used to switch between transmitting and receiving. ADDC™ (Automatic Data Direction Control) ADDC™ is the best method for switching between transmission and receiving when using 2-wire RS-485. When using ADDC™, additional code is not required to switch between data transmitting and receiving, since the switching mechanism is managed automatically by the board’s built-in intelligent hardware mechanism. This means that RS-485 programming using ADDC™ mode is just as simple and straightforward as RS-232 or RS-422 programming. 4-4 CP-132U Series User’s Manual 5 Chapter 5Connection Cables and Cable Wiring In serial data communications, the term DTE stands for Data Terminal Equipment, such as a PC’s COM1/2, serial printers, and terminals. The term DCE stands for Data Communication Equipment, such as modems. RS-422/485 Pinouts and Cable Wiring RS-422 Interface The RS-422 standard uses a balanced voltage digital interface to allow 9600 bps communication over cables of up to 4000 feet in length. Ten receivers can be connected to any one driver for broadcasting systems. RS-485 Interface The RS-485 standard is an enhanced version of the RS-422 balanced line standard. It allows multiple drivers and receivers to work on a multidrop network. A maximum of 32 drivers and 32 receivers can be set up on a multidrop network. The CP-132UL Series supports both 2-wire half-duplex and 4-wire full-duplex RS-485 communications. In 2-wire RS-485, Data+/- pins are used for both data transmitting and receiving, depending on the RTS signal. 5-2 CP-132U Series User’s Manual Connection Cables and Cables Wiring Pinouts RS-422/485 pinouts for CP-132UL Series CP-132UL (RS-422/485) RS-422 and 4-wire RS-485 Port 1 Port 2 8 9 10 11 12 21 22 23 24 2 3 4 5 14 15 16 17 18 CTS-(A) RxD-(A) RTS-(A) RTS+(B) RxD+(B) TxD-(A) SGND CTS+(B) TxD+(B) TxD-(A) SGND CTS+(B) TxD+(B) CTS-(A) RxD-(A) RTS-(A) RTS+(B) RxD+(B) 2-wire RS-485 Data-(A) Data+(B) Data-(A) Data+(B) CBL-M25M9x2 CP-132U Series User’s Manual 5-3 RS-422 pinouts for CP-132UL Series CP-132UL (RS-422) 1 2 3 4 5 6 7 8 9 TxD-(A) TxD+(B) RxD+(B) RxD-(A) GND RTS-(A) RTS+(B) CTS+(B) CTS-(A) 2-wire RS-485 pinouts for CP-132UL: CP-132UL (2-wire RS-485) 1 2 3 4 5 6 7 8 9 ----Data+(B) Data-(A) GND --------- 4-wire RS-485 pinouts for CP-132UL Series CP-132UL (4-wire RS-485) 1 2 3 4 5 6 7 8 9 5-4 TxD-(A) TxD+(B) RxD+(B) RxD-(A) GND --------- CP-132U Series User’s Manual Connection Cables and Cables Wiring Cable Wiring RS-422 Point-to-point CP-132UL 2 TxD+(B) 1 TxD-(A) 3 RxD+(B) 4 RxD-(A) 5 GND RS-422 Broadcasting RS-422 Device RxD+(B) RxD-(A) TxD+(B) TxD-(A) GND CP-132UL 2 TxD+(B) 3 RxD+(B) 1 TxD-(A) 4 RxD-(A) 5 GND RS-422 Device 1 RxD+(B) TxD+(B) RxD-(A) TxD-(A) GND RS-422 Device N RxD+(B) TxD+(B) RxD-(A) TxD-(A) GND CP-132UL – RS-422 with Handshaking CP-132UL 2 TxD+(B) 1 TxD-(A) 3 RxD+(B) 4 RxD-(A) 5 GND 7 RTS+(B) 6 RTS-(A) 8 CTS+(B) 9 CTS-(A) RS-422 Device RxD+(B) RxD-(A) TxD+(B) TxD-(A) GND CTS+(B) CTS-(A) RTS+(B) RTS-(A) CP-132UL – 2-wire RS-485 CP-132UL 3 Data+(B) 4 Data-(A) 5 GND RS-422 Device Data+(B) Data-(A) GND CP-132U Series User’s Manual 5-5 Multidrop 2-wire RS-485 (half-duplex) CP-132UL Master 3 Data+ 4 Data5 GND RS-485 Device 1 Slave Data+ DataGND RS-485 Device N Slave Data+ DataGND Multidrop 4-wire RS-485 (full-duplex) CP-132UL Master 2 TxD+(B) 1 TxD-(A) 3 RxD+(B) 4 RxD-(A) 5 GND RS-485 Device 1 Slave RxD+(B) RxD-(A) TxD+(B) TxD-(A) GND RS-485 Device N Slave RxD+(B) RxD-(A) TxD+(B) TxD-(A) GND See the section “RS-485 Programming” in the “Serial Programming Tools” chapter for more details on RS-485 programming. 5-6 CP-132U Series User’s Manual Connection Cables and Cables Wiring Impedance Matching and Termination Resistors When using RS-422/485 serial communications, an electrical signal that travels through two different resistance junctions in a transmission line will sometimes give rise to signal reflection due to the impedance mismatch. Signal reflection causes signal distortion, which in turn contributes to communication errors. The solution to this problem is to establish the same impedance at the ends of the transmission line, as in the line itself, by terminating the ends of the line with resistors. CP-132U Series User’s Manual 5-7 6 Chapter 6Troubleshooting Common CP-132UL Series problems and possible solutions are listed below. If you still have problems after reading this chapter, contact your dealer or Moxa for help, or use the Problem Report Form at the end of this manual to report problems to your dealer. General Troubleshooting 1. The MOXA PCI board cannot be detected by the MOXA driver while installing the driver. Hardware causes and solutions: a. The board is not installed in the computer. Please install it. b. The board is not properly plugged into the system. If this is the case, re-plug the board in a 32-bit PCI. It is also possible that a slot has malfunctioned. In this case, try other slots until you find one that works. c. The motherboard does not have an available IRQ for the CP-132UL Series board. In this case, enter the BIOS and make sure there is an availalbe IRQ under PCI/PnP settings. 2. The MOXA board and driver are activated but cannot transfer (transmit/receive) data. Hardware Causes and Solutions: a. Make sure the cable wiring is connected correctly. Refer to the “Connection Cable and Cable Wiring” chapter for correct cable connections. b. The cable or the board are probably defective. Try other ports, cables, or boards to verify this, or use the PComm Diagnostic utility to test the MOXA board’s and port conditions. If Diagnostic reports an error, replace the faulty components. Software Causes and Solutions: 6-2 a. CP-132UL Series boards will check the line status (CTS) before transmitting data if the RTS/CTS flow control feature is set to Enable in the configuration or application program. Refer to the Connection Cables and Cable Wiring chapter for proper wiring diagrams, and check the line status of the suspected port using the diagnostic LED indicators on the mini tester. b. The board controlling application might not be correctly written according to the corresponding API of the operating system. To check this problem, run another existing and known good application or use the utilities provided by Moxa (such as Pcomm Terminal emulator or HyperTerminal under Windows NT and Windows 95/98). CP-132U Series User’s Manual Technical Reference Windows NT This section is specifically for troubleshooting under Windows NT. For general problems and solutions, see the previous section, “General Troubleshooting.” 1. After the system reboots, the error message “Another driver in the system, which did not report its resources, has already claimed the interrupt used by xxx.” appears in the Event Log. This indicates the MOXA board was found, but the IRQ is conflicting with another adapter. Please check the PCI BIOS IRQ settings first and then select an IRQ that is available. 2. After the system reboots, the error message “Cannot find any configured MOXA Smartio/Industio Series board!” appears in the Event Log. Make sure the PCI board is seated firmly in the expansion slot. 3. The COM number of the CP-132U Series conflicts with others. The COM numbers of different boards happen to be the same. Try changing the COM number mappings. 4. Windows NT system panic (blue screen). The possible reason is an IRQ or memory conflict with other ISA Bus adapters, like LAN and SCSI boards, or the system BIOS. Refer to the corresponding problem in the previous section, “General Troubleshooting,” for possible solutions. CP-132U Series User’s Manual 6-3 Windows 95/98 This section is specifically for troubleshooting under Windows 95/98. For general problems and solutions, see the previous section, “General Troubleshooting.” 1. 2. The system fails to find the CP-132U Series board! z The board(s) is(are) not plugged properly. z The slot the boards are plugged into is defective. Try another slot until you find one that works. z The board might be defective. After the system reboots, the error message “CP-132U Series (BusNo=x, DevNo=x, Port1=COMx) interrupt number is invalid!” appears. This indicates that the MOXA board was found, but the IRQ conflicts with another adapter. Make sure the MOXA board’s IRQ does not conflict with other adapters’ IRQ. Check the PCI BIOS IRQ settings and select an available IRQ for MOXA boards. 6-4 CP-132U Series User’s Manual A Appendix A Technical Reference Specifications Bus interface Number of ports Max.

The IRQ and I/O address hardware configuration is automatically assigned by the PCI BIOS. This means that you must first plug in the board before installing the driver software. As opposed to ISA slots, different PCI slots in the same PC may have different bus numbers and device numbers with respect to the PCI specifications. The same PCI board will have different system configurations if switched to a different PCI slot; this is called slot-sensitive or slot-dependent. This may also apply to PCI slots in a PC with a different motherboard, which may use different device number sets. For example, some use 17, 18, 19, and 20 for identifying the respective PCI slots, but some use 11, 12, 13 and 14. Due to slot-dependency, it is necessary to re-configure the driver software once the board is plugged into different PCI slots. Up to 4 CP-132UL Series boards are allowed in one system. When installing more than one board, please remember the order the boards are installed to distinguish the installed boards from each other. .
